Tight enough to stay in place and not shift, loose enough to not have it get pressed into the BB's path.

The size of these chambers has to be tailored to the projectile bore diameter and barrel length, rather than having sound bouncing around randomly in these aforementioned chambers. The second is to form a seal as good as practical, forcing the expanding gasses to fill the cavities and in turn lower the pressure present at the muzzle; most suppressors will have a preliminary chamber to aid in this. Though it will not matter in Airsoft, it also relieves some of the pressure from the baffles to extend service life.

Again the lack of design knowledge and how to implement it properly keeps individuals from being successful in adequate attenuation, but that is a good thing I suppose since we don't want people building real ones either. So I guess if someone wants to change the sound and maybe lower the report a bit, foam will work.
That's a bit much, comparing airsoft suppressors to the real steel ones. Lol, show off.
